I remember the Devils one where they were mispronouncing each player's name.

You know, as i'm thinking about it, there was actually an episode in the final season about a minor league hockey player and they thought his injury was due to fighting. The whole episode was kind of the debate between fighting and hockey and whether or not it's relevant and necessary. I think he ended up signing an NHL contract at the end of the episode or something like that. Obviously their writers liked hockey, they snuck it in whenever they could.
